Let's take a look at the first one...
1) The Head Boy/Girl (The Nerd)
How to spot: They constantly talk about their past successes as the top student of the school and how they spent their summer reading Shakespeare. There's a very high chance they are still wearing their school uniform or a close resemblance of it.
Background: They went to a grammar school and they took part in various charity activities to demonstrate their deep sense of care for the community. They are quite keen to fulfil the role at university.
Most likely to say: 'Sir, I've read the last 3 chapters of the book, do you think it'd be a good idea to make flashcards to enhance my learning?'
'Professor Smith, what is tomorrow's homework?'
'Not going out tonight, I have to do the reading for the next 5 lectures and start my essay which is due in 3 months, can't you see?! I'm busy.'
Make friends? Erm... I highly doubt it because this type of student doesn't even share notes. No exceptions.
2) The Gap Year Student (The Traveller)
How to spot: He/She is wearing bracelets from Colombia, travel pants from Cambodia, t-shirt from India.
Background: They were once pretty standard, one day they realised that there's more to life than sitting on the couch watching television. Packed their bags and set off to numerous adventures around the world for 12 months straight. They only got back a day before freshers' week. Most likely to hit the road again as soon as the holiday breaks roll around.
Most likely to say: 'Sorry mate. I can't make it to the drinks tonight. I'm flying to Burma straight after my tutorial to see my girlfriend. I will be back in 10 days.'
'I have been to Brazil last year, I had such a great time, the people were so nice.'
'I am going to Indonesia, Malaysia and Thailand this summer to visit my friends.'
Make friends? Of course. Very useful for travel tips, fun to be around, open-minded and may even give you a yellow fever.
3) The Facebook Buddy
(The Facebook Buddy does not particularly like real-life interactions with other human beings).
How to spot: Quite challenging to spot because they rarely leave their room. You may meet one or two at the grocery store because they need to stock up on snacks and fizzy drinks.
Background: Having grown up in the social media age, he/she will only be your Facebook buddy. You invited them for a night out once, they kindly rejected without a specific reason. This one does not understand the importance of real-life human interaction. He/She, however, is skilled at the usage of emoticons and also speaks the 'Internet'.
Most likely to say: 'Hi, how are you? :)' 'I am good thanks, what are you up to?' 'Oh, cool! :P'
Make friends? Mehhh, he/she will like a couple of your pictures, statuses every now and then but will never actually talk to you in real life. You will also occasionally receive candy crush requests. You might as well accept the friend invitation and block them from your feed. Easy peasy! You, on the other hand, truly don't recall how both of you met in the first place.
4) The Stoner
How to spot: Red eyes, normally wears a bandana, relaxed demeanour and unkempt hair.
Background: Doesn't actually remember. His friends call him Weezzle, the shizzle ma' nizzle... he also has several posters of Bob Marley on the wall in his room.
Most likely to say: 'Weed is the solution to world peace.'
'Who has my lighter? Oh never mind, it was in my hand.'
'I am so freaking high right now.'
Make friends? Yes, they are always cool and chilled.
5) The Rich Kid
How to spot: Normally found at Jack Wills stores or Selfridges. Sometimes they hang out with Lady Gaga and Paris Hilton.
Background: Dad is a the director of a commercial bank and mum is a lawyer. His older brother is a doctor and sister is an investment banker. From a relatively posh town, you know something like Cambridgeshire, Marlington... One or the other.
Most likely to say: 'Drinks on me tonight!' 'It's only £700! Not a big deal. I'll get it.' 'Excuse me, where is the Gucci store?'
Make friends? Duhhh?! See 'most likely to say'.
6) The Party Animal (That One Girl)
How to spot: It is said they go out 8 days a week, sometimes 9 when they feel like it. Normally found at the most mainstream clubs and in all house parties you go to. However, it is very rare that you see them around campus.
Background: Normally from well known cities or relatively small towns. Looking for some excitement in life, their motto is 'YOLO'. It is their way of life. They went to a standard school and standard college.
Most likely to say: 'OMG, you look gorgeous in this dress!' 'Girls picture, hashtag #girls #nightout #loveyou #boobsandshit' 'Where is my vodka?'
Make friends? Why not?! They give you excellent club reviews and generally good fun to be with, sometimes overly dramatic. Hard to keep up the friendship if you're more of a slippers-and-cuppa kind of person.
7) The Networker (The Social Whore)
How to spot: Mostly seen at networking events, social gatherings and business meetings.
Background: He knows everyone. Everyone knows him. He's the at the centre of the attention most of the times entertaining the crowd. This individual is keen to expand his network.
Most likely to say: 'Hi, my name is...' 'Nice to meet you!' 'How you doing?'
Make friends? Yes. Useful for party and job contacts. If you are looking for somebody, don't use social media sites, he's your man.
8) The Hobbyist (The Sportive Guy/Gal)
How to spot: They always hold a sports' bag on the way to training or coming back from one.
Background: They were captain of the football/netball team back in high school, involved in numerous sports activities and always practicing. The coach loves him/her. A true jewel to the sports' community.
Most likely to say: 'Can't go out this Friday, got foot-ball practice all day Saturday.' 'Can't make it next Wednesday, got a match on that day.' 'Sorry mate, can't come. I have training this weekend.'
Make friends? Well, unless you're a hobbyist yourself, that's fine. If not, then what's the point? Sports > You.
9) The Ghost
How to spot: You occasionally bump into them on campus at the most random times. Usually seen on a Sunday night, when they return to university from home.
Background: Pretty standard dude. Nobody exactly knows the reason why they're usually absent. At times he appears out of nowhere, you sometimes can't recognise him.
Most likely to say: 'I've just been busy.' 'I spent the last 3 nights at my girlfriend's place.' 'I went home for the weekend, and going home next weekend as well.'
Make friends? Yes. Their empty room can be utilised to temporarily store your excessive amount of items. They won't notice it.
10) The Life-Planner
How to spot: They constantly check their diaries or calendar phone to remind themselves what they need to do. Usually complains to you how they didn't manage to finish a task.
Background: They've got it all mapped out. They're going to travel around the world for 8 months after university, then work at a corporate organisation for 2 years before being promoted to a manager. They'll get married at the age of 27, have a kid at 30, a second one at 32. Their diaries are fully planned of activities and executed like a robot, most of the time.
Most likely to say: 'You are 2 minutes late, you totally ruined my plans.' 'Let me check my diary if I am free that day.' 'Sorry, my next free day is in two weeks, until then I can't meet you.'
Make friends? They make you feel totally unprepared. You don't even know what to wear in the morning and eat for breakfast, let alone travelling, kids and employment.
